A book written about the West Memphis Three is headed to the big screen.

The Facebook page for the "Devil's Knot" movie says it will premiere on May 9th.

The movie, starring Reese Witherspoon and Colin Firth, focuses on the brutal deaths of Stevie Branch, Christopher Byers, and Michael Moore, and the arrests and convictions of the three teens accused - Damien Echols, Jessie Misskelley, and Jason Baldwin

The movie is a docu-drama, meaning some parts of the story have been changed.
